This package defines the API for plugging in bytecode libraries for usage by Hibernate. Hibernate uses these bytecode libraries in three scenarios:
Currently, both CGLIB and Javassist are supported out-of-the-box.
Note that for field-level interception, simply plugging in a new BytecodeProvider is not enough for Hibernate to be able to recognize new providers. You would additionally need to make appropriate code changes to the org.hibernate.intercept.Helper class. This is because the detection of these enhanced classes is needed in a static environment (i.e. outside the scope of any org.hibernate.SessionFactory .
Note that in the current form the ability to specify a different bytecode provider is actually considered a global settings (global to the JVM).
